When your HVAC system stops working as it should, you may start wondering how much longer your heating and air conditioning system will last. With this in mind, you may start to wonder when you will need to replace your HVAC system. 

There are several signs that your HVAC system has reached its end of life, and as HVAC experts, we’re here to go over some of them. These are just 5 signs that it’s time to replace your HVAC system. 

1. Your system is 10 to 15 years old, or older.

One of the first tell-tale signs that it’s time to consider making the upgrade is that your HVAC system is 10 to 15 years old or older. As with most things, over time, your HVAC system begins to lose efficiency and internal components begin to break. This not only means that you’ll be paying more for your energy bill, but you may also be paying more for repairs.

In addition to that, the HVAC systems of today are designed much better than they were in the past. High-efficiency air conditioners, for example, are expected to reach much higher standards today than they were just 10 years ago. In this way, your older HVAC system is costing you more in energy costs than necessary.

2. You’ve noticed a significant spike in your energy bills.

In line with older systems not being designed as well for energy efficiency, the age of your system alone is likely causing an increase in your energy bills. As mentioned previously, the older the system, the older the internal components and the less likely your system will run efficiently. 

As such, each year your HVAC systems, you will likely see a subtle increase in the costs of running your system. However, as your system really starts to break down, those costs may rise significantly. If that is the case, it is a clear sign to upgrade your system as soon as possible. 

3. Things are getting a bit dusty.

Outside of energy efficiency, it’s worth being concerned about your HVAC system if you notice that there’s more dust in your home than usual. Why does this happen? Excessive dust is often due to your system’s decreased ability to remove dust and debris from inside your home.

Newer and effective HVAC systems will work to remove the dust and debris from your home. Issues with dust, specifically, may be due to gaps in your ductwork, often due to age. Unfortunately, finding these gaps can be challenging and is often best addressed through a full replacement of your ductwork and, thereby, your HVAC system. 

4. You’re hearing strange sounds or noticing unusual smells.

Much like dust, some other causes for concern include strange sounds or unusual smells coming from your system. Strange sounds, for instance, may indicate that something has gone wrong with one of your internal components. If you hear any grinding or squealing noises coming from your system, it’s time to contact an HVAC professional.

In the same way, unusual smells, for example, can be indicative of several potential issues, from electrical issues to mold in your ductwork. Whatever the cause may be, it’s worth having it investigated. With that being said, a properly functioning HVAC system should not make strange sounds or give off unusual smells, and if it does, it may be time for it to be replaced.

5. The cost of repairing your AC is astronomical.

If you’ve noticed any of the aforementioned issues, from excessive dust to unusual smells, you may have already taken the steps to call an HVAC professional and get an estimate for repairs. While many HVAC problems can be solved through repairs, if those repairs are costly, you may want to consider if the repairs are worth the price.

An older HVAC system is comparable to an older vehicle. There often comes a time when the number of repairs required to keep the vehicle running outweigh the value of the vehicle, or trying to continue keeping it maintained well enough for use. When you reach this point with your HVAC system, a full system upgrade may be the next best choice.
